A system and method are described for provisioning a wireless service on a wireless network. The wireless network includes: at least one of an in-network service element and an out-of-network service element; and a provisioning-manager module (SPM) for activating the at least one of the service elements for servicing a user, wherein the SPM counts a number of subscribers of the at least one service element, and performs one of the following: (a) provisions the user, if the number of subscribers is below a threshold count level, or (b) de-provisions another user, if the number of subscribers is above the threshold count level. The SPM only provisions a service element when that service element is requested by the user.
